Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.04056 |
| Opus 5 | $0.00026 | $0.02028 |
| Sonnet 5 | $0.00010 | $0.00811 |
| Haiku 4.5 | $0.00005 | $0.00406 |
Grade C, and why
kora-teacher scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 461 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kora Teacher — Learn Kora Framework from Scratch
Kora sub-skill — obey the kora-v1 meta rules on every task: R0 ensure
.kora-agent/docs+examples are cloned · R1 read this sub-skill before writing code · R2 Kora APIs only — no Spring/Micronaut/Quarkus, no invented annotations or config keys · R3 journal any incorrect Kora usage. Add comments/Javadoc only if asked.
Purpose: Guide new users through Kora Framework learning path using ONLY official sources — no invented explanations, no assumptions.
Activation: When user wants to learn Kora from zero, asks beginner questions, requests tutorials/guides, or needs step-by-step implementation help.
⚠️ CORE RULE — Source Hierarchy (STRICT)
ALWAYS follow this order — NO DEVIATIONS:
1. Guides (.kora-agent/kora-docs/mkdocs/docs/en/guides/<guide>.md)
↓
2. Documentation (.kora-agent/kora-docs/mkdocs/docs/en/documentation/<module>.md)
↓
3. Guide apps (.kora-agent/kora-examples/guides/java|kotlin/<app>/)
↓
4. Example apps (.kora-agent/kora-examples/examples/java|kotlin/<app>/)
NEVER:
- Invent explanations not found in sources
- Assume Kora behavior without checking docs
- Use Spring/Micronaut/other framework analogies
- Skip guide apps when implementing examples
WHY: Kora has unique compile-time patterns. Wrong mental model from day 1 = hard to fix later.
Quick Start — First Session
Task Progress:
- [ ] 1. Assess user's current level (Java/Kotlin? Framework experience?)
- [ ] 2. Clone Kora docs + examples if not present
- [ ] 3. Start with getting-started.md guide
- [ ] 4. Implement getting-started-app together
- [ ] 5. Explain every annotation, every line
- [ ] 6. Move to next guide in sequence

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kora-teacher is a skill published in the GitHub repository kora-projects/kora-skills (1 stars, last pushed 11d ago), licensed Apache-2.0. It adds 51 tokens to every session and 4,056 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
